Research

After a postdoc at Ohio State (2001-2003), I continued my scientific career at the Synchrotron Light National Laboratory (LNLS) and Nanotechnology National Laboratory (LNNano) in Brazil (2004-2015) as a researcher, group leader, and deputy director.

In 2015, I returned to Ohio State by joining the welding engineering program within the Department of Materials Science and Engineering. I teach welding metallurgy and additive manufacturing in addition to being the director of the Manufacturing and Materials Joining Innovation Center (Ma2JIC).

My team research focuses on understanding the evolution of the materials associated with conventional and advanced joining and additive manufacturing operations. We approach both the technological and fundamental aspects of joining and additive manufacturing metallurgy, and we have a strong record in process and materials modeling and advanced characterization.

In recent years, we have devoted our effort to the study of advanced steels, stainless steels and Ni-based alloys fusion welding, additive manufacturing, solid state joining (friction stir welding), and the development and application of advanced in-situ techniques associated with electron microscopy and synchrotron x-ray diffraction to unveil the fundamentals of phase transformations on structural and functional materials. We are currently engaged in the development of fast-acting ICME-based solutions for the automotive and aerospace industries that allow us to take advantage of process and materials modeling for the optimization of complex multi-materials joining and additive manufacturing operations.

Approach to diversity and inclusion

I grew up and developed my career while moving across different cultures and countries. Moving to a different country is not easy - the senseless paperwork is painful - but it is definitively worth the effort. You get to experience new cultures and learn new languages. This path has given me an appreciation for the diversity of cultures and ethnicities and  has made me quite aware of the good and bad things about my own culture and the other cultures I have had the privilege of experiencing.

As part of my history, I have been part of and, in some cases led, small and large teams from different countries/cultures. This has allowed me to learn first hand the value of diversity. It is quite simple. If you want a winning team, make it as diverse (in all aspects) as you can. However, just a diverse team does not make the cut. You need to make it inclusive. All members need to feel that they are an important and welcomed member of the team.

You might not know

I love trying food from different origins. As my daughter says, it is hard to find something that I do not like.
